Abstract

A person detection unit in an image processing apparatus is input an image captured by an image capturing unit and detects a person from the input image. An observation target determination unit determines an observation target in the image captured by the image capturing unit according to an action taken by the person detected by the person detection unit.

Claims

1. An image processing apparatus comprising:

an obtaining unit configured to obtain an image;

a detection unit configured to detect one or a plurality of persons from the obtained image; and

a determination unit configured to determine an observation target according to a predetermined action taken by the detected person from an area different from an area corresponding to the person who takes the predetermined action.

2. The image processing apparatus according to claim 1, wherein the determination unit specifies a content of the action based on at least one of a motion and a movement of the detected person.

3. The image processing apparatus according to claim 1, wherein the determination unit determines the observation target according to an action taken by a person who has a predetermined feature amount among the detected persons.

4. The image processing apparatus according to claim 1, wherein the determination unit determines the observation target according to an action taken by a person whose time length existing in the image is equal to or more than a predetermined time length among the detected persons.

5. The image processing apparatus according to claim 1, further comprising a sensor information obtaining unit configured to obtain information from a position sensor,

wherein the determination unit determines the observation target according to an action taken by a person corresponding to information from the position sensor among the detected persons.

6. The image processing apparatus according to claim 1, wherein the determination unit determines the observation target based on a change in an existing position of the detected person in the image.

7. The image processing apparatus according to claim 1, further comprising a specification unit configured to specify a moving path of the detected person from the image obtained by the obtaining unit,

wherein, in a case where a change occurs in a moving path of the person specified by the specification unit, the determination unit determines an area in which a person does no longer pass through due to the change as the observation target.

12. The image processing apparatus according to claim 1, further comprising,

a recording unit configured to record an image obtained by the obtaining unit after determination of the observation target by the determination unit.

13. The image processing apparatus according to claim 1, further comprising,

a control unit configured to change an image capturing range of an image capturing unit which captures the image according to determination of the observation target by the determination unit.

14. The image processing apparatus according to claim 1, further comprising,

a control unit configured to control resolution so that resolution corresponding to an area of the observation target determined by the determination unit becomes higher than resolution before the determination.

8. An image processing apparatus comprising:

an obtaining unit configured to obtain an image;

a detection unit configured to detect an object from the obtained image; and

a determination unit configured to determine an observation target according to the detected object from an area different from an area corresponding to the object.

9. The image processing apparatus according to claim 8, wherein the determination unit determines the observation target based on a change in an existing position of the detected object in the image.

10. The image processing apparatus according to claim 8, further comprising a specification unit configured to specify a moving path of the detected object from the image obtained by the obtaining unit,

wherein, in a case where a change occurs in a moving path of the object specified by the specification unit, the determination unit determines an area in which an object does no longer pass through due to the change as the observation target.

11. The image processing apparatus according to claim 8, wherein the determination unit determines a person who exists in a direction indicated by an arrow mark detected by the detection unit as the observation target.

15. A method for processing an image performed by an image processing apparatus, the method comprising:

inputting for obtaining an image;

detecting a person from the obtained image; and

determining an observation target according to a predetermined action taken by the detected person from an area different from an area corresponding to the person who takes the predetermined action.

16. The method according to claim 15, wherein

the observation target is determined according to an action taken by a person who has a predetermined feature amount among the detected persons.

17. The method according to claim 15, wherein the observation target is determined based on a change in an existing position of the detected person in the image.

18. A method for processing an image performed by an image processing apparatus, the method comprising:

obtaining an image;

detecting an object from the obtained image; and

determining the observation target according to the detected object from an area different from an area corresponding to the object.

19. The method according to claim 18, wherein

the observation target is determined based on a change in an existing position of the detected object in the image.

20. The method according to claim 18, further comprising specifying a moving path of the object detected from the obtained image,

wherein, in a case where a change occurs in a moving path of the specified object, an area in which an object does no longer pass through due to the change is determined as the observation target.

21. A computer-readable storage medium storing a computer-executable program, the program comprising:

obtaining an image;

detecting a person from the obtained image; and

determining an observation target according to a predetermined action taken by the detected person from an area different from an area corresponding to the person who takes the predetermined action.

22. A computer-readable storage medium storing a computer-executable program, the program comprising:

obtaining an image;

detecting an object from the obtained image; and

determining an observation target according to the detected object from an area different from an area corresponding to the object.
